How do I add an alias for a naked domain with OpenShift?

问题

How can I make my naked domain to point to my Openshift application?

Can it be done in the Openshift online dashboard or it can only be configured through the rhc utility? However I am not sure which the steps to do it.

It's a two-step process:

1. First, make sure that you have a DNS provider that offers support for naked CNAMES, then and add one or more CNAME entries that point to the URL that OpenShift provided for your application (APPNAME-NAMESPACE.rhcloud.com or similar).
2. Next, use the rhc alias command to let OpenShift know that you would like your application to be made available whenever a request is received via any of the CNAMEs configured in your DNS. This step can also be completed on the Web via your OpenShift app management dashboard.

For example, if you had an OpenShift application named wordpress that you wanted available at wordup.com, your rhc alias command might look like this:

rhc alias add wordpress wordup.com

The answer was simple,

1) Add the Openshift DNS as A Record target.

2) Then add alias to the Openshift app like example.com

With that when example.com is accessed it will go to the app hosted in Openshift.
